What is this?

This is an experimental interface for finding
Wikipedia articles to
read when you're doing in-depth research on a topic.
Type a topic above to see links to Wikipedia articles that
match — English only, for now. As you type, the green bar below
the input box will fill with matching Wikipedia links sorted by how
popular they are. You can hit enter to go directly to the most
popular result on Wikipedia. To the right of the green bar, the links
are organized by subject area based on the words they have in common.

Special features

The system is kind of like the "autocomplete" feature that many search boxes have, but with a few
extras:

The results are ranked based on how often they have been viewed on Wikipedia recently,
so topical suggestions will tend to show up first.

The results include internal matches. So for example,
to learn about famous expeditions,
search for expedition and you'll get
"Lewis and Clark Expedition", "Kon-Tiki expedition", and so forth;
kennedy will show you famous Kennedys.

If you're really not sure of your query, type a question mark
("?") after it. The system will try to find terms that mean
the same thing as your query. For example,
barrel maker? yields "cooper",
ringing in the ears? yields "tinnitus", and
museum in paris? yields "louvre".
Failing that, the system will try to find a term in Wikipedia that sounds like your query.
For example,
noomoanya? brings up "pneumonia".

Technical notes

This service uses the Datamuse API on a vocabulary of approximately
10 million Wikipedia titles and redirects.
